Dual micropipette assay. (A) Two cells in suspension (1 and 2) are held under weak aspiration by micropipettes, and placed in contact (B; Video 1). The formation of contact is checked (C) after displacement of the right pipette. (D) Second cell is held by the micropipette under strong aspiration. (E–I) First cell is held by the micropipette and the aspiration applied is increased as the right micropipette displaced, step by step, until the adherent cells are separated (I; Video 2).
